Speaker with auxiliary air hole

Abstract

A speaker applicable to various electronic devices includes a speaker body including a magnet and a diaphragm having a voice coil interacting with the magnet, the magnet and the diaphragm being sequentially received therein; at least one main hole defined through a rear surface of the speaker where a speaker sound is not output, such that air generated in the speaker according to vibration of the diaphragm is discharged therethrough; and at least one auxiliary air hole defined through a predetermined location of a side surface of the body to communicate with an inside of the body, such that air within the speaker is additionally discharged therethrough.

1. A speaker comprising:
 a speaker body including a magnet and a diaphragm having a voice coil interacting with the magnet, the magnet and the diaphragm being sequentially received therein; 
 a plurality of main holes defined through a rear surface of the speaker body where speaker sound is not output, such that air flow generated in the speaker according to a vibration of the diaphragm is discharged therethrough; and 
 at least one auxiliary air hole defined within a predetermined location of a side surface of the speaker body to communicate with an inside of the speaker body, such that air within the speaker is additionally discharged therethrough, 
 wherein the speaker body includes a plate type air guide protruding from the speaker body around the at least one auxiliary air hole, the plate type air guide guiding air discharged from the at least one auxiliary air hole. 
 
     
     
       2. The speaker of  claim 1 , wherein the air guide includes a recess to form a flange along an edge thereof, the flange being formed toward the space to which air discharged from the auxiliary air hole is guided. 
     
     
       3. The speaker of  claim 1 , wherein the auxiliary air holes are defined through two sides of the speaker body facing each other. 
     
     
       4. The speaker of  claim 3 , wherein the at least one auxiliary air hole is formed as one long hole shape and the plurality of main holes are circular holes arranged at regular intervals. 
     
     
       5. The speaker of  claim 1 , wherein the at least one auxiliary air hole is formed as one long hole shape and the plurality of main holes are circular holes arranged at regular intervals. 
     
     
       6. A portable terminal comprising a speaker, the speaker comprising:
 a speaker body for outputting sounds in response to received signals; 
 a plurality of main holes defined through a rear surface of the speaker body; and 
 at least one first air hole defined at a side surface of the speaker body to communicate with an inside of the speaker body, such that air within the speaker is discharged therethrough, 
 wherein the speaker body includes a plate type air guide protruding from the speaker body around the at least one first air hole, the plate type air guide guiding air discharged from the at least one first air hole. 
 
     
     
       7. The portable terminal of  claim 6 , the speaker further comprising the plurality of main holes defined through a rear surface of the speaker body, such that air generated in the speaker according to a vibration of the diaphragm is discharged therethrough. 
     
     
       8. The portable terminal of  claim 6 , wherein the air guide includes a recess to form a flange along an edge thereof, the flange being formed toward the space to which air discharged from the first air hole is guided. 
     
     
       9. The portable terminal of  claim 6 , wherein the first air holes are defined through two sides of the speaker body facing each other. 
     
     
       10. The portable terminal of  claim 9 , wherein the at least one first air hole is formed as one long hole shape and the plurality of main holes are circular holes arranged at regular intervals. 
     
     
       11. The portable terminal of  claim 6 , wherein the at least one first air hole is formed as one long hole shape and the plurality of main holes are circular holes arranged at regular intervals. 
     
     
       12. A speaker comprising:
 a speaker body for outputting sounds in response to received signals; 
 a plurality of main holes defined through a rear surface of the speaker body; and 
 at least one first air hole defined at a side surface of the speaker body to communicate with an inside of the speaker body, such that air within the speaker is discharged therethrough, 
 wherein the speaker body includes a plate type air guide protruding from the speaker body around the at least one first air hole, the plate type air guide guiding air discharged from the at least one first air hole. 
 
     
     
       13. The speaker of  claim 12 , the speaker further comprising the plurality of main holes defined through a rear surface of the speaker body, such that air generated in the speaker according to a vibration of the diaphragm is discharged therethrough. 
     
     
       14. The speaker of  claim 12 , wherein the first air holes are defined through two sides of the speaker body facing each other.
